15000BTU AC w 2000 watt generator

[glennco]

The sticker in my 15000 BTU Dometic says 20 amps minimum (2400 watts), and 70 amps startup (8400 watts) (the LRA value). My Honda EU2000i is rated for 2000 watts surge and 1650 watts continuous. I'd be afraid to run it at the ragged edge for sustained periods. It powers the camper fine as long as the AC isn't on.

I’m not sure the LRA rating means startup current. I mean our campers only have 50A power as do pedestals at campgrounds. In that case the AC wouldn’t ever start.

We have a Yamaha 2000watt generator and it ran out old 13.5k btu A/C with ease once we installed an easy start. It didn’t have a chance without one. But, we knew that our old A/C unit had a running wattage of about 1500watts.

I’d love to be able to power this 15k btu A/C unit with the same generator with an easy start. After all, upgrading generators is pricey, can’t they can be heavy.

I’ll climb up on the roof tomorrow evening and see if I can find a sticker that gives the wattage, or even amperage.

I’ll let everyone here know what I find.

thanks again,
Paul

The 15K Colman A/C unit on my trailer pulls about 12-13amps running based on the Power Control System display. That is with the converter breaker off and no other AC loads.

LRA does indeed mean "Locked Rotor Amps". This is the highest instantaneous current drawn by the compressor during start-up. This is a rating, so reality may be slightly different due to a number of factors.

To see this yourself, go to about the 12 minute mark in MicroAir's video. The high current only lasts a very short time.
